Tokyo, Japan and Cambridge, UK, 19 December 2024 – Nxera Pharma Co., Ltd. (“Nxera” or “the Company”; TSE 4565) – formerly known as Sosei Group or Sosei Heptares – and Shionogi & Co., Ltd. (“Shionogi”) today announce that QUVIVIQ™ (daridorexant) 25 and 50 mg has been launched and is now available in Japan as a new treatment for adults with insomnia. QUVIVIQ™ is an oral Dual Orexin Receptor Antagonist (DORA) for the treatment of insomnia that selectively binds to receptors of the wake-promoting neuropeptide orexin (OX1R and OX2R), inhibiting excessive wakefulness and facilitating the transition to sleep. Nxera Pharma Japan Co., Ltd. (a wholly owned subsidiary of Nxera Pharma) is the approval holder and will be responsible in part for provision of drug product. Shionogi will be solely responsible for distribution and sales activities for QUVIVIQ™ in Japan under the commercial partnership agreement with Nxera Pharma announced on 1 October 2024. For Nxera, reaching this important milestone highlights its ability to develop novel therapeutics for patients in Japan and reinforces its ambition to be a partner of choice for companies looking to develop and commercialize new therapeutics for the Japanese market. As a new pillar, Shionogi is focusing on the ‘QOL disease area,’ which is less affected by trends. Starting with the launch of QUVIVIQ™, Shionogi is working to strengthen the ‘QOL disease area’ as a solid pillar. Together, Nxera and Shionogi are committed to deliver QUVIVIQ™ as quickly as possible as a product that has the potential to meet the needs of insomnia patients for a long time to come. –END– Notes to Editors Product Information Product nameQUVIVIQ™ 25 mg, 50 mgNon-proprietary namedaridorexantIndicationInsomniaDosage regimenThe usual adult dosage is 50 mg of daridorexant to be taken orally once daily immediately before bedtime.

About Insomnia DisorderInsomnia disorder is defined as difficulty initiating or maintaining sleep, causing clinically significant distress or impairment in important areas of daytime functioning. As defined this impact on sleep quantity or quality should be present for at least three nights per week, lasts for at least three months, and occurs despite an adequate opportunity to sleep. Insomnia is a condition of overactive wake signaling and studies have shown that areas of the brain associated with wakefulness remain more active during sleep in patients with insomnia. According to a survey by Japan’s Ministry of Health, Labour and Welfare in 2018, about 20% of Japanese adults struggle to get enough rest from sleep. Insomnia as a disorder is quite different from a brief period of poor sleep, and it can take its toll on both physical and mental health. It is a persistent condition with a negative impact on daytime functioning. Research has shown that poor quality sleep can affect many aspects of daily life, including the ability to concentrate, mood, and energy levels. The goal of treatments for insomnia is to improve sleep quality and quantity, as well as daytime functioning, while avoiding adverse events and next-morning residual effects. Current recommended treatment of insomnia includes sleep hygiene therapy, cognitive behavioral therapy, and pharmacotherapy.
